A saucer is a small type of dishware, a plate that is specifically used with and for supporting a cup – a cylindrical cup intended for coffee or a half-sphere teacup for tea. Additionally, the saucer is a distant cousin to the plate. The saucer has a raised centre with a depression sized to fit a mating cup. The saucer is useful to protect surfaces from possible damage due to the heat of a cup, and to catch overflow, splashes, and drips from the cup, so protecting both table linen and the user sitting in a free standing chair who holds both cup and saucer. The saucer also provides a convenient place for a damp spoon, as might be used to stir the drink in the cup in order to mix sweeteners or creamers into tea or coffee. Some animals, including cats, may also be fed from saucers.
Although often part of a place setting in a dinner set, teacups with unique styling are often sold with matching saucers, sometimes alone, or as part of a tea set, including a teapot and small dessert plates. A set of four is typical for a tea set. Some people also drink their tea out of saucers to cool it down.
